“Bandwidth in computer networking refers to the data rate
supported by a network connection or interface. One most commonly
expresses bandwidth in terms of bits per second (bps). The term
comes from the field of electrical engineering, where bandwidth
represents the total distance or range between the highest and
lowest signals on the communication channel (band).“Bandwidth represents the capacity of the connection. The
greater the capacity, the more likely that greater performance will
follow, though overall performance also depends on other factors,
such as latency…”
